Take off every Zig!
I don't know how to do that exactly. The closest I could come up with would be to leave the array undefined and use a helper function to fill it in, but that has slightly different semantics since the memcpy is a little more explicit:
undefined
memcpy
fn init_array(target: anytype, items: ?[]const std.meta.Elem(@TypeOf(target))) void { const T = std.meta.Elem(@TypeOf(target)); if (items) |slice| { std.mem.copy(T, target, slice); std.mem.set(T, target[slice.len..], std.mem.zeroes(T)); } else { std.mem.set(T, target, std.mem.zeroes(T)); } } var foo: [50]u8 = undefined; init_array(&foo, "foo"); var a = A{.foo = undefined}; init_array(&a.foo, "foo");
Good solution. I haven't seen std.meta.Elem before so I'm going to go read up on that. Thanks!
